Using Imagery to Find Lines of Symmetry
The video gives definition of line symmetry and asks students to identify it within several images. The line of symmetry is drawn on each image after it is shown with out so instructor can easily pause video to give students the opportunity to come up with their own solutions. (01:29)
A figure has symmetry when it can be folded so two halves match or are identical. Examples are shown of line symmetry in the world around us. Practice activities in the video show images and students decide whether it has vertical, horizontal, or no line of symmetry.

Sea Star Regeneration
Sea stars (star fish) have an amazing ability to regenerate lost limbs. In this video Professor Blake Barron from Santa Barbara City College describes the process of sea star regeneration. (01:07)
How Does the Earth Change? Part 1
In this brief video, the narrator discusses weathering and erosion.
The Hawaiian chain of islands, made up of six main islands plus two smaller ones, stretches for more than 1,500 miles through the heart of the Pacific Ocean. It is a place of idyllic beauty. But it is also a land of volcanic fury, raging mountaintop blizzards, dangerous rockslides, monster waves, and even tsunamis. This professionally-made video from PBS Nature provides a beautiful display of the constructive and destructive forces that create our planet. (51:00)
The Chemical Basis of Life: Summary
This is a video slide show accompanied by text:"Living organisms use only a small fraction of the known chemical elements to carry out all of their biological functions. Six elements make up more than 99% of matter in living systems: hydrogen, carbon, nitrogen, oxygen, phosphorous, and calcium. Five elements are found in much smaller amounts: sodium, magnesium, sulfur, chlorine, and potassium. Finally, 14 elements are known as "trace" elements because living organisms require them in minute quan
Dr. Loopy's Blinding you with Science #2: Layers and erosion
This is episode #2 of Blinding you with Science. This series was produced to assists elementary students in understanding science concepts. In this episode Dr. Loopy and his friends discuss how layers are formed in nature and how erosion works. Run time 12:09.
Discovering Hidden Habitats: Monterey Bay Aquarium & NOAA
This video was produced by NOAA's Ocean Media Center for the National Marine Sanctuary Program. It shows deep ocean habitat and marine life found in the Monterey Bay National Marine Sanctuary, which is a Federally protected marine area offshore of California's (U.S.) central coast. (6:04)
Salmon swim upstream to the waters where they were born for the final race of their lives. They get one chance to breed in their lifetime. Watch in this video how perilous this journey can be. This video might also be used with a lesson about animal instinct vs learned behavior. Run time 03:45.
Solar Energy Concentrator
This video demonstrates how solar energy can be focused with a curved mirror. Once focused this energy can be used to cook food, sterilize water even create electricity. Includes an explanation of energy, power, joules, and watts. Examples of radiant, heat, chemical and kinetic energy are given.
Includes links to directions for constructing a simple solar concentrator.
Shows both the reactions and properties of the alkali metals, such as lithium, sodium, and potassium. Video with narration. Grades 5-12. Includes closed captioning. 2:28 min.
Science Fair Project (Hot Ice)
This is a brief video of a school science fair project that won first place. Sodium Acetate was used in the project to create "hot ice", a liquid substance that instantly turns solid when touched. The video is set to music with brief descriptions written on the screen. No narration or explanation provided. Explanation: The reaction is exothermic and is often found in hand warmers. Run time 03:14.
A History of Flying
Video on flying airplanes with some science and history used.
The History of Flight
Provides the history of flight, from the Wright brothers to modern aviation.
Work/Energy Problem with Friction
A conservation of energy problem where all of the energy is not conserved. This video, which is suitable for high school students, starts with a black screen because the instructor, in his conversational tone, uses it as a 'chalkboard.' Instructor uses different colors for clarification. Run time 10:04.
Nuclear Power - How it Works
This excellent seven-and-a-half mini-documentary shows through narration and computer animation how a nuclear generating station works.
Where Do You Get Your Energy
Cells extract energy from sugar to produce ATP, the molecular fuel that powers all life processes. This interactive activity adapted from the Exploratorium delves into the processes that enable cells to unlock the energy contained in the foods we consume. We often use the term "energy" as an informal shorthand for our ability to stay alert and complete tasks. In fact, the presence of energy-rich molecules and our cells' ability to obtain, process, and use this energy is critical to life.
